Keycloak

Keycloak

Description

Keycloak is an open-source Identity and Access Management (IAM) solution that makes it simple to add authentication and authorization to your applications and services. It eliminates the need to handle user storage or complex authentication logic. With Keycloak, developers can quickly integrate secure login, user federation, and fine-grained access control.

Features

  • Authentication & Authorization: Add secure login and access control with minimal setup.
  • User Federation: Connect to existing LDAP or Active Directory servers to manage users.
  • Strong Authentication: Support for multi-factor authentication and advanced security protocols.
  • User Management: Centralized user registration, profile management, and password handling.
  • Fine-Grained Authorization: Define access policies and permissions with advanced rules.
  • Extensibility: Build custom providers, adapters, and extend functionality through APIs.
  • Deployment Options: Run locally, via Docker, or integrate into cloud-native environments.

Technology Stack

  • Java (Keycloak server and adapters)
  • Docker (official containerized images)
  • Quarkus (runtime for high performance and low memory footprint)
  • CNCF Ecosystem (community and governance)

Requirements

  • Java installed for local builds
  • Docker (optional, for containerized deployment)
  • Access to LDAP, Active Directory, or other identity providers (optional for federation)
